Systems and methods for selectively removing hydrogen sulfide from a feed gas stream. The systems include an absorber-heat exchanger (ABHEX) assembly configured to exchange thermal energy between a mixed stream and a thermal management fluid stream. The ABHEX assembly defines a mixed stream volume and a thermal management fluid stream volume. The ABHEX assembly includes an isolation structure that maintains fluid separation between the mixed stream and the thermal management fluid stream and facilitates thermal communication between the mixed stream and the thermal management fluid stream. The ABHEX assembly is configured to receive and to mix the feed gas stream and a lean solvent stream to generate the mixed stream, to separate the mixed stream into a product gas stream and a rich solvent stream, and to cool the mixed stream. The methods include methods of operating the systems.

Hydrocarbon gas treatment systems and methods. The hydrocarbon gas treatment systems include a feed gas supply system configured to provide a feed gas stream and a hydrogen sulfide removal system configured to separate the feed gas stream into a product gas stream and an acid gas stream. The hydrocarbon gas treatment systems also include a heat exchanger configured to cool the acid gas stream to generate a cooled acid gas stream and an acid gas enrichment system configured to separate the cooled acid gas stream into a treated gas stream and an enriched acid gas stream. The methods include providing a feed gas stream, separating the feed gas stream into a product gas stream and an acid gas stream, cooling the acid gas stream to generate a cooled acid gas stream, and separating the cooled acid gas stream into a treated gas stream and an enriched acid gas stream.
